For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

L-carnitine is an amino acid needed to transport fats into the mitochondria (the place in the cell where fats are turned into energy). Adequate energy production is essential for normal heart function. Several studies using 1 gram of L-carnitine two to three times per day showed an improvement in heart function and a reduction in symptoms of angina.1, 2, 3Coenzyme Q10 also contributes to the energy-making mechanisms of the heart. Angina patients given 150 mg of coenzyme Q10 each day have experienced greater ability to exercise without experiencing chest pain.4 This has been confirmed in independent investigations.5

People with CHF have insufficient oxygenation of the heart, which can damage the heart muscle. Such damage may be reduced by taking L-carnitine supplements.1 L-carnitine is a natural substance made from the amino acidslysine and methionine. Levels of L-carnitine are low in people with CHF;2 therefore, many doctors recommend that those with CHF take 500 mg of L-carnitine two to three times per day.

Most L-carnitine/CHF research has used a modified form of the supplement called propionyl-L-carnitine (PC). In one double-blind trial, people using 500 mg of PC per day had a 26% increase in exercise capacity after six months.3 In double-blind research, other indices of heart function have also improved after taking 1 gram of PC twice per day.4 It remains unclear whether propionyl-L-carnitine has unique advantages over L-carnitine, as limited research in animals and humans has also shown very promising effects of the more common L-carnitine.5

Dose: 2 grams dailyL-carnitine is an amino acid important for transporting fats that can be turned into energy in the heart. Clinical trials have reported that taking L-carnitine (4–6 grams per day) increases the chance of surviving a heart attack.1, 2, 3 In one double-blind trial, individuals with suspected heart attack were given 2 grams of L-carnitine per day for 28 days.4 At the completion of this study, infarct size, as well as the number of nonfatal heart attacks, was lower in the group receiving L-carnitine versus the placebo group. Double-blind research using L-carnitine intravenously also shows promise.5

Dose: 2 grams dailyIn double-blind trials, supplementation with L-carnitine and propionyl-L-carnitine (a form of L-carnitine) has increased walking distance in people with intermitting claudication. Walking distance was 75% greater after three weeks of L-carnitine supplementation (2 grams taken twice per day), than after supplementation with a placebo, a statistically significant difference. In the study using propionyl-L-carnitine, improvement occurred on in the those who could not walk 250 meters to begin with. In that group, maximum walking distance increase by 78% with propionyl-L-carnitine supplementation compared with a 44% increase in the placebo group, also a statistically significant difference. The amount of propionyl-L-carnitine used was 1 gram per day, increasing to 2 grams per day after two months, and 3 grams per day after an additional two months, if needed. The results of this trial have been confirmed in a large European trial.

L-carnitine is another supplement that has lowered TGs in several clinical trials.1, 2 However, the effect of carnitine is unpredictable, and some individuals have experienced an increase in triglyceride levels after receiving this supplement.3 Some doctors recommend 1–3 grams of carnitine per day, in the form known as L-carnitine.

In double-blind trials, supplementation with either L-carnitine and propionyl-L-carnitine (a form of L-carnitine) has increased walking distance in people with intermittent claudication. Walking distance was 75% greater after three weeks of L-carnitine supplementation (2 grams taken twice per day), than after supplementation with a placebo, a statistically significant difference.1 In the study using propionyl-L-carnitine, improvement occurred only in those who could not walk 250 meters to begin with. In that group, maximum walking distance increased by 78% with propionyl-L-carnitine supplementation compared with a 44% increase in the placebo group, also a statistically significant difference.2 The amount of propionyl-L-carnitine used was 1 gram per day, increasing to 2 grams per day after two months, and 3 grams per day after an additional two months, if needed. The results of this trial have been confirmed in a large European trial.3

L-carnitine has been given to people with chronic lung disease in trials investigating how the body responds to exercise.1, 2 In these double-blind trials, 2 grams of L-carnitine, taken twice daily for two to four weeks, led to positive changes in breathing response to exercise.

Dose: Refer to label instructionsL-carnitine is needed by heart muscle to utilize fat for energy. Some,1, 2 but not all, preliminary trials report that carnitine reduces serum cholesterol.3 HDL cholesterol has also increased in response to carnitine supplementation.4, 5 People have been reported in controlled research to stand a greater chance of surviving a heart attack if they are given L-carnitine supplements.6 Most trials have used 1 to 4 grams of carnitine per day.

In one report, deficient levels of L-carnitine were found in five consecutive people with MVP.1 One of these people was given L-carnitine (1 gram three times per day for four months) and experienced a complete resolution of the symptoms associated with MVP.

Deficiency of L-carnitine, an amino acid, is associated with the development of some forms of cardiomyopathy.1 Inherited forms of cardiomyopathy seen in children may be the most responsive to therapy with L-carnitine.2, 3 Whether carnitine supplementation helps the average person with cardiomyopathy remains unknown. Nonetheless, some doctors recommend 1 to 3 grams of carnitine per day for adults of average weight.

In one study, 12 people with Raynaud’s disease were given L-carnitine (1 gram three times a day) for 20 days.1 After receiving L-carnitine, these people showed less blood-vessel spasm in their fingers in response to cold exposure.

In a double-blind study, supplementing with the combination of propionyl-L-carnitine (a form of L-carnitine) and acetyl-L-carnitine (2 grams of each per day) for six months significantly improved erectile function in elderly men with erectile dysfunction associated with low testosterone levels. Propionyl-L-carnitine and acetyl-L-carnitine were significantly more effective than testosterone treatment.1

L-carnitine is a substance made in the body and also found in supplements and some foods (such as meat). It appears to be necessary for normal functioning of sperm cells. In preliminary studies, supplementing with 3–4 grams per day for four months helped to normalize sperm motility in men with low sperm quality.1, 2 While the majority of clinical trials have used L-carnitine, one preliminary trial found that acetylcarnitine (4 grams per day) may also prove useful for treatment of male infertility caused by low quantities of immobile sperm.3

L-carnitine is an amino acid needed to properly utilize fat for energy. When people with diabetes were given DL-carnitine (0.5 mg per 2.2 pounds of body weight), high blood levels of fats—both cholesterol and triglycerides—dropped 25 to 39% in just ten days in one trial.1

Dose: 0.25 mg per 2.2 lbs (1 kg) of body weightL-carnitine is an amino acid needed to properly utilize fat for energy. When people with diabetes were given L-carnitine (0.5 mg per 2.2 pounds of body weight), high blood levels of fats—both cholesterol and triglycerides—dropped 25 to 39% in just ten days in one trial.1

Dose: 100 mg per 2.2 lbs (1 kg) of body weight daily, up to a maximum of 4 grams per day

In a double-blind study, supplementation with L-carnitine for eight weeks resulted in clinical improvement in 54% of a group of boys with ADHD, compared with a 13% response rate in the placebo group.1 The amount of L-carnitine used in this study was 100 mg per 2.2 pounds of body weight per day, with a maximum of 4 grams per day. No adverse effects were seen, although one child developed an unpleasant body odor while taking L-carnitine. Researchers have found that this uncommon side effect of L-carnitine can be prevented by supplementing with riboflavin. Although no serious side effects were seen in this study, the safety of long-term L-carnitine supplementation in children has not been well studied. This treatment should, therefore, be monitored by a physician.

Dose: 50 mg per kilogram of body weight per day (half in the morning, half in the evening)
In a double-blind trial, supplementing with L-carnitine resulted in a modest improvement in disease severity in children with autism spectrum disorders. The amount of L-carnitine used was 50 mg per kilogram of body weight per day (half in the morning and half in the evening) for three months.1

In a double-blind study, supplementing with the combination of propionyl-L-carnitine (a form of L-carnitine) and acetyl-L-carnitine (2 grams of each per day) for six months significantly improved erectile function in elderly men with erectile dysfunction associated with low testosterone levels. Propionyl-L-carnitine and acetyl-L-carnitine were significantly more effective than testosterone treatment.1

L-carnitine is required for energy production in the powerhouses of cells (the mitochondria). There may be a problem in the mitochondria in people with CFS. Deficiency of carnitine has been seen in some CFS sufferers.1 One gram of carnitine taken three times daily for eight weeks led to improvement in CFS symptoms in one preliminary trial.2 Supplementation with 6 grams of L-carnitine per day for four weeks also improved fatigue in a preliminary study of patients with advanced cancer.3 Similar improvements were seen in another study of patients with advanced cancer given up to 3 grams of L-carnitine per day for one week.4

L-carnitine, which is normally manufactured by the human body, has been popular as a potential ergogenic aid (i.e., having the ability to increase work capacity), because of its role in the conversion of fat to energy.1 However, while some studies have found that L-carnitine improves certain measures of muscle physiology, research on the effects of 2 to 4 grams of L-carnitine per day on performance have produced inconsistent results.2 L-carnitine may be effective in certain intense exercise activities leading to exhaustion,3 but recent studies have reported that L-carnitine supplementation does not benefit non-exhaustive or even marathon-level endurance exercise,4, 5 anaerobic performance,6 or lean body mass in weight lifters.7

Dose: Refer to label instructionsThe amino acid L-carnitine is thought to be potentially helpful for weight loss because of its role in fat metabolism. In a preliminary study of overweight adolescents participating in a diet and exercise program, those who took 1,000mg of L-carnitine per day for three months lost significantly more weight than those who took a placebo.1 A weakness of this trial, however, was the fact that the average starting body weight differed considerably between the two groups. A double-blind trial found that adding 4,000 mg of L-carnitine per day to an exercise program did not result in weight loss in overweight women.2

Dose: Refer to label instructionsIn a double-blind trial, supplementing with L-carnitine (1,050 mg each morning for six months) improved lung function and overall asthma control, compared with a placebo, in Egyptian children with asthma.1

L-carnitine is made in the body from the amino acids lysine and methionine, and is needed to release energy from fat. It transports fatty acids into mitochondria, the powerhouses of cells. In infancy, and in situations of high energy needs, such as pregnancy and breast-feeding, the need for L-carnitine can exceed production by the body. Therefore, L-carnitine is considered a "conditionally essential" nutrient.1
